The public will get extra time to have their say on a proposed merger of Constellation Energy Group Inc. with Exelon Corp. in light of the companies’ settlement struck with Gov. Martin O’Malley last month.

The Maryland Public Service Commission said Tuesday it would give until Feb. 2 for members of the public to submit comments on the merger. The state Office of People’s Counsel requested the extension last week.

The PSC and the public have the right to weigh in because the merger would transfer ownership of utility Baltimore Gas and Electric Co. from Baltimore-based Constellation (NYSE: CEG) to Chicago-based Exelon (NYSE: EXC).

The settlement added promises for nearly 300 megawatts of new power generation and new construction of a headquarters for Constellation in downtown Baltimore.
